Shipping Information
Returns/Refunds/Exchanges

The Supercaliber SLR 9.8 XT is an ultra-light XC mountain bike that's ready to lay down rubber on race day. Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus lay-up that gives you all the stiffness you crave, and none of the weight. XC courses get rowdier every year, so it's equipped with a 110 mm fork and 80 mm of IsoStrut rear suspension to smooth your roll without kicking pedalling efficiency to the wind. It's all topped off with carbon wheels, a carbon cockpit and Shimano's trail-trusted XT drivetrain.

It's right for you if...

Party laps are fun, but you're ready to race. You want a cross-country steed that sprints up climbs, hammers to the finish and feels good doing it thanks to 80 mm of IsoStrut rear suspension. From wheels to cockpit, you crave carbon and you want the most meticulous high-mod carbon lay-up we offer on a mountain bike.

The tech you get

A featherweight, high-modulus SLR OCLV Mountain Carbon frame with modern XC geometry. 110 mm of front suspension from a Fox Performance 34 step-cast fork with Float EVOL air spring, GRIP damper, dual remote lockout and 80 mm of IsoStrut rear suspension from a RockShox SIDLuxe shock. A Shimano XT 12-speed drivetrain, Bontrager Kovee Elite 30 carbon wheels, carbon Bontrager RSL Integrated bar/stem combo, Bontrager Line Dropper post and Shimano Deore XT M8100 hydraulic disc brakes.

The final word

The Supercaliber SLR 9.8 XT is bred for racing and comes from a pedigree of champions. You get our top carbon XC full-suspension frame dripping with carbon components and the trail-trusted reliability of Shimano's XT drivetrain.

Why you'll love it

  1. You get a 110 mm fork and 80 mm of IsoStrut rear suspension that partners with slacker, capable geometry for handling the roots and rocks of modern XC courses
  2. You don't have to compromise stiffness for weight savings thanks to the SLR OCLV Mountain Carbon frame that's intensely light, stiff and responsive
  3. IsoStrut gives you tunable, damped suspension without missing out on efficiency for hammering up climbs at top speed
  4. Pivotless seat stays save on weight and actively bend to help soak up trail chatter
  5. Upgraded components, like Shimano's XT drivetrain and a step-cast Fox 34 fork, give you the advantage you want, where you want it
